When it comes to buzz, food reigns supreme.
"Out of everything we cover, food and dining are the most talked-about things—even more than media and entertainment," said Ed Keller, president at Engagement Labs and CEO of The Keller Fay Group.
The Keller Fay Group recently polled people to gauge fast food's top restaurants for word of mouth. The research and analytics firm asked 17,863 Americans to record which fast food chains they spoke about that day. They then used this national cross section to estimate the average number of total offline impressions per month.
About 30 percent of people polled daily had at least one conversation about fast food on the days they were polled.
Keller stressed the importance of in-person conversations for generating a restaurant's sales.
